The present study was carried out from March 2000 to June 2005 by interviewing many people from several parts of Brazil. It was aimed at assessing the level of knowledge on technical graphic symbols used for identification of commands and operation controls, and support in agricultural machines. The main customers involved in the process from the project of the agricultural machine to its use and support were interviewed. Results suggest that the knowledge of the graphic symbols meaning is quite reduced among the main customers involved in the process.
